IMPROVEMEN] lN THE MANUFACTURE 0F CASKS, BARRELS, AND KEGS.

Specification forming part of Letters Patent No. 55,1 37, dated May 29, 1866.

that the following is a full and correct de-v scription thereof', reference being had to the annexed drawings, making part of this speciiieation, and to the letters of reference thereon.

My invention relates more particularly to casks, barrels, and kegs used for the transportation of crude and refined petroleum and similar iiuids.

Gasks used for this purpose have been subject to leakage to such extent as to compel the use of tin or other metallic cans for shipping refined petroleum upon long voyages.

My invention consists, first, in an improved cask having its joints tongued and grooved with tongues and grooves ot' a V or other similar form, the tongue being a little larger than the groove, so that when the hoops are driven tightly the tongue is forced into the groove to make a tight joint; second, in an improved cask the joints ot' which are tongued and grooved and cemented with glue or a similar gelatinous cement suitable to resist the penetration ot' liquid hydrocarbons.

Figure l of the drawings is a top view of the cask; Fig. 2, a cross-section; Fig. 3, avertical section through the heads and staves, and Fig. 4L a section of a stave.

The staves a are each made with a tongue, b, and a groove, c, as shownin the drawings. The heads d are also made with tongues c and grooves f, to preserve the barrels from leakage and to stiften the heads Dowel-pins g may also be used in putting the head-pieces together. v

I believe that pails and tubs have been made with recessed joints; but I am not aware that any barrel, cask, or keg having a bilge and closed at both ends, so as to be suitable for or ot any use in the transportation of liuids, has ever before been made with joints in the manner I have described.

I make the staves and heads ot' good seasoned wood, and tongue and groove them before trussing them, or they may be tongued and grooved after being bent.

For the purpose of more completely securing the joints against the penetrationof hyldrocarbon fluids I also cement the staves and heads together at the joints with glue or Similar gelatinous cement. To do this, the cash may be taken to pieces after it is made, and hot glue being spread over the joints, the cask is immediately put together and the hoops driven tight. I have discovered that thick casks of seasoned wood thus made will effectually hold hydrocarbon liquids for storage and transportation.

The 'additional expense ot` a cask made as herein described is very small in comparison with the great economy of substitu tin g a cheap wood eask for the expensive metallic cans used for thc transportation of relned petroleum on long voyages.

I claim as of my invention and improvement in casks, barrels, and kegs used for the transportation of iiuids-l 1. The improved cask, substantially as described, having its joints made with tongues y and grooves, substantially in the way and for the purposes hereinbefore described andset forth.

2. In combination with the joints of a tongued and grooved cask, a coating or Stuffing of glue or similar gelatinous cement in the joints, substantially as hereinbefore described.

JOSHUA MERRILL.
